1. Typo: "absense"

Location: "Notes on precision" section, in the introductory paragraph.

Sentence: "In the absense of a suitable high-precision ephemeris provider, some functions might return an error if called with NOVAS_FULL_ACCURACY."

Correction : "absence"

2. Typo: "conjuction"

Location: "Notes on precision" section, under "Prerequisites to precise results" subsection, in the "Gravitational bending" paragraph.

Sentence: "Without it, there is no guarantee of achieving the desired μas-level precision in general, especially when observing near massive planets (e.g. observing Jupiter's or Saturn's moons, near conjuction with the host planet)."

Correction : "conjunction"

3. Typo: "commnad-line"

Location: "Incorporating Solar-system ephemeris data or services" section, in the introductory paragraph.

Sentence: "Or, you can use the JPL HORIZONS system (via the commnad-line / telnet or API interfaces) to generate custom ephemerides (SPK/BSP) for just about all known solar systems bodies, down to the tiniest rocks."

Correction: "command-line"

4. Typo: "NOVAS_DEBUF_OFF"

Location: "Runtime debug support" section, in the table and the paragraph following it.

Table Entry: "NOVAS_DEBUG_OFF No debugging output (default)" (The text uses NOVAS_DEBUF_OFF in the explanation, but the table correctly shows NOVAS_DEBUG_OFF).

Sentence: "The debug messages can be disabled by passing NOVAS_DEBUF_OFF (0) as the argument to the same call."

Correction : "NOVAS_DEBUG_OFF"

5. Typo: "atmopsheric" & "Improvemements"

Location: "SuperNOVAS added features" section, under "New in v1.4" subsection.

Sentence: "Improvemements to atmopsheric refraction modeling."

Correction: "atmospheric" and "Improvements"

6. Typo: "NOVAC C 3.1"

Location: "Refinements to the NOVAS C API" section, in the last paragraph.

Sentence: "Changed the standard atmospheric model for (optical) refraction calculation to include a simple model for the annual average temperature at the site (based on latitude and elevation). This results is a slightly more educated guess of the actual refraction than the global fixed temperature of 10 °C assumed by NOVAC C 3.1 regardless of observing location."

Correction: "NOVAS"

7. Typo: "SuperNOVAS will try follow"

Location: "Release schedule" section, in the first paragraph.

Sentence: "SuperNOVAS will try follow a quarterly release schedule."

Correction: "will try to follow"

8. Typo: "Minor Planer Center"

Location: "SuperNOVAS added features" section, under "New in v1.2" subsection.

Sentence: "For example, the Minor Planer Center (MPC) publishes accurate orbital elements for all known asteroids and comets regularly."

Correction: "Minor Planet Center"
